This invention relates to improvements in' shells or other projectilesfor guns.

The object of the invention is to provide a projectile for guns wherebythe friction'between the sides of the projectile and the inside of thegun-barrel will be reduced to a minimum.

A further object is to construct a projectile of this character whichwill be simple in construction and may be inexpensively produced.

With these and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement of parts,as will be more fully described, and particularly pointed out in theappended claims.

In the accompanying drawings, Figure 1 is a side elevation of aprojectile constructed in accordance with the invention. Fig. 2 is alongitudinal sectional view, and Fig. 3 is a vertical cross-sectionalview of the same.

Referring more particularly to the drawings, 1 denotes a projectilewhich may be in the form of a shell or in the form of a solid shot orbullet. As shown in the drawings, the projectile is in the form of asolid shot having an elongated slightly-tapering body portion formed atone end with a point 2 and at its other end an annular shoulder orflange 2. In the sides of the shot are formed a series of longitudinalradially disposed grooves or channels 3, which extend from near theinner flanged end of the shot to the forward end of the tapered portionof the same. The grooves or channels 3 are dovetail shape incross-section, and in each of the same is arranged a strip or block 4 ofwood or other suitable material. The blocks 4 are of dovetail shape incross-section and are adapted to be slipped into the grooves or channels3 from the forward or pointed end of the bullet. The thickness of thestrips or blocks 4 is somewhat greater than the depth of the grooves 3,thereby causing the outer sides of the blocks to project radially fromthe sides of the shot to the height of the collar or flange 2.

The forward ends of the blocks are beveled off to correspond with thepointed end of the shot.

In the drawings are shown four of the blocks 4, arranged atdiametrically opposite points around the'shot. This number, may,however, be increased or diminished, as desired.

When the shot is placed in the gun-barrel, the blocks engage the innersides of the same, thereby preventing the body of the shot from engagingthe inner side of the gun-barrel, except at its rear flanged orshouldered end, thus greatly diminishing the friction between the shotand the inner wall of the gunbarrel, and in order to further eliminatesuch friction the blocks are saturated with oil or other suitablelubricant. The flange or shoulder 2 is necessary on the inner end of theshot to overcome the windage between the shot and the inner wall of thegun-barrel.

While wood has been particularly described as the material of which theblocks are composed, it is obvious that I may form the same of anysuitable porous material which will absorb oil or other lubricant.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extended explantion.

Various changes in the form, proportion, and the minordetails ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A projectile consisting of a body portion pointed at one end andprovided with longitudinally disposed dovetailed grooves formedcircumferentially in the sides of said body portion and extending fromnear one end of the body portion to the taper of the point, and woodenstrips of dovetail form inserted in said grooves and having appliedthereto a lubricating material, said wooden strips extending beyond thesurface of the body portion, substantially as described.

2. A projectile consisting of a slightly-tapered body portion, pointedat one end and provided with an annular flange or shoulder formed on therear or inner end of the same, longitudinally-disposed dovetail groovesextending from the shoulder to the point, and

oiled Wooden blocks or strips arranged in said my hand in presence oftwo subscribing Witgrooves, the inner ends of said blocks bearingnesses.

eminst said shoulder and the outer ends bein 1 tgpered to lie flush withthe surface of th: HOMER BEALE point of the projectile, substantially asde- Witnesses:
